Abstract: 1,257,809. Cutting devices. GERRARD INDUSTRIES Ltd. 8 April, 1969 [4 April, 1968], No. 16307/68. Heading B4B. [Also in Divisions B3, E1-E2 and F2] In a package-binding mechanism comprising a base with a sealing station, a hingeably mounted sealing head, adjacent the sealing station and between a gripping device and a tensioning device, and a tension-releasing device (see Division F2), a cutter comprises a fixed blade 44 and a moving blade 42, pivoted about a screw 43 and held by a spring 45 in the open position. Movement of the sealing head (13), Fig. 1 (not shown), away from the base causes a spring-loaded projection (60), Fig. 1 (not shown), to contact a pivoted pawl 39, causing a toe 40 to depress the blade 42.

Abstract: 1289963 Cathode-ray tube displays EMI Ltd 2 Oct 1969 [11 Oct 1968] 48373/68 Heading H4T In a cathode-ray tube oscilloscope in which the beam is deflected in orthogonal directions at relatively high and low frequencies respectively, video signals are gated to the beam intensity control electrode during short intervals in each of the lower frequency deflection periods the times at which gating occurs being changed progressively in successive periods and further signals to form one or more markers on the display are gated to the intensity control electrode during respective selected high frequency deflection periods in each lower frequency deflection period. The invention is described in connection with an arrangement in which each of a plurality of video signals to be displayed is compared with the sawtooth ramp voltage producing the higher frequency deflection, (vertical line deflection) each video signal "standing-on" a progressively higher shift voltage so that during each period of the sawtooth a series of output voltages for application to the beam intensity control electrode is derived as the amplitude of each video signal coincides with the instantaneous sawtooth amplitude. For satisfactory display of slowly varying signals such as video signals a horizontal (lower frequency) deflection period between, e.g. 0-1 second and 20 seconds, depending on the rate of variation, is required but, because of the decay time of the screen phosphor fixed information such as markers will have faded by the end of the horizontal period and the present invention is concerned with the solution of this difficulty. As shown, the marker signal is produced by comparing a (manually adjustable) reference voltage from source 12 with the horizontal deflection waveform (of about 50 c.p.s.) from source 10, in a computer 11 which supplies via gate 13 a beam bright-up pulse having a duration equal to the period of the vertical (line) deflection generator 4 (of relatively high frequency) during each period of the horizontal deflection waveform so that a marker comprising a vertical line is produced on the display. The video signals each "standing-on" a different shift voltage are supplied from sources 6 1 -6 n  to respective comparators 5 1 -5 n  in which they are compared with the vertical deflection waveform from source 4 to produce a sequence of output signals via respective gates 7 1 -7 n  during each period of the deflection waveform and the outputs from the gates are supplied to the beam intensity control (modulator) via a further gate 9 which is "opened" for the duration of one vertical deflection period at progressively later instants during successive periods of the horizontal deflection wave from source 10 under the control of the output of a comparator 15 supplied with the latter deflection wave and with a sawtooth of long period (e.g. suitable for the display of slowly varying waveforms). More than one marker may be displayed and the oscilloscope 1 may utilize electromagnetic deflection instead of electrostatic deflection.

Title: Vehicle monitoring radar apparatus

Abstract: 1315533 Pulse radar PYE Ltd 24 June 1971 [24 June 1970] 30695/70 Heading H4D A vehicle monitoring pulse radar provides an output indicative of a characteristic of the vehicle or its motion only when an echo pulse is coincident with a timing pulse generated a predetermined time after the transmitted pulse. In a radar speed trap generator 50 produces pulses spaced at 2 Ás. which are fed to shaper 52 which diverts them along a delay line 54 whose length is determined by the position of switches 28, 30, 32 which earth respective taps on the line. The shaper output thus comprises the generated pulse followed by a timing pulse reflected from the short circuit. The pulse pair passes to a p.i.n. switch 56 which modulates the output of a Gunn diode oscillator 58. The transmitted pulses are coupled into the receiving antenna 26. If a reflected signal is coincident with a timing pulse detector 60 passes the signal to mixer 62 which extracts the Doppler signal. The timing pulse spacings selected by delay line 54 are chosen to correspond to echoes from the near, centre or far lanes of a three-lane carriageway. The Doppler signal passes through a zero-crossing detector 72 to gate 70 which is enabled by a monostable 68 triggered by detector 66. The pulsed output of the gate 70 is counted and provides a direct reading of the vehicle velocity on a three figure seven segment display. The apparatus is aligned at precisely 45 degrees to the carriageway using the following procedure. At a convenient point the radar is aligned along the traffic flow and flux gate magnetometer 78 rotated until a null output is indicated by lamp 44. The magnetometer is then rotated through 45 degrees. At the measuring station (i.e. at a more discrete point) the radar apparatus is rotated until the magnetometer output is nulled. The magnetometer also provides an inhibit signal to gate 68 if the apparatus is incorrectly aligned. Switches are provided for enabling transmission or display and also for providing a continuous signal to the modulator which signal acts as a test signal equivalent to a vehicle travelling at 30 m.p.h.
